Karenne Tun shared photos of bleaching at Pulau Hantu and Raffles Lighthouse on facebook.
Besides hard corals, even sea anemones were bleaching!
She said "Reminiscent of the 1998 bleaching event - but perhaps a shade less severe. Its still early days yet; Sea Surface Temperatures (SST) hovering around 31degC. Hoping that it will not get warmer than that. Did 2 surveys today - at Pulau Hantu and Raffles Lighthouse, to assess the severity of the bleaching. Working out potential recovery index now."
